If Trouble Arises
WARNING
■Never tamper with the air bag/pretensioner systems and always have
your Toyota dealer perform all servicing and repairs:
Self-servicing or tampering with the systems is dangerous. An air bag/pre-
tensioner could accidentally activate or become disabled causing serious
injury or death.
■
If the tire pressure monitoring system warning light illuminates or
flashes, or the tire pressure warning beep sound is heard, decrease
vehicle speed immediately and avoid sudden maneuvering and
braking:
If the tire pressure monitoring system warning light illuminates or
flashes, or the tire pressure warning beep sound is heard, it is danger-
ous to drive the vehicle at high speeds, or perform sudden maneuvering
or braking. Vehicle drivability could worsen and result in an accident.
To determine if you have a slow leak or a flat, pull over to a safe position
where you can check the visual condition of the tire and determine if you
have enough air to proceed to a place where air may be added and the
system monitored again by your Toyota dealer or a tire repair station.
■Do not ignore the TPMS Warning Light:
Ignoring the TPMS warning light is dangerous, even if you know why it
is illuminated. Have the problem taken care of as soon as possible
before it develops into a more serious situation that could lead to tire
failure and a dangerous accident.

If Trouble Arises
Seat Belt Warning LightThe seat belt warning light
turns on if the driver or front
passenger’s seat is occupied

If the driver or front passen-
ger’s seat belt is unfastened
(only when the front passen-
ger’s seat is occupied) and
the vehicle is driven at a
speed faster than about 12
mph (20 km/h), the warning
light flashes. After a short
time, the warning light stops
flashing, but remains illumi-
nated.

Tire Pressure Monitoring
System Warning Light
When the warning light illu-
minates, and the warning
beep sound is heard (about
3 seconds), tire pressure is
too low in one or more tires.
Inspect the tires and
adjust to the specified
inflation pressure
(→ P. 446).
• Perform tire pressure adjustment when the
tires are cold. Tire
pressure will vary
according to the tire
temperature, there-
fore let the vehicle
stand for 1 hour or
only drive it 1 mile
(1.6 km) or less
before adjusting the
tire pressures. When
pressure is adjusted
on hot tires to the
cold inflation pres-
sure, the TPMS
warning light/beep
may turn on after the
tires cool and pres-
sure drops below
specification.

(if equipped)
Also, an illuminated
TPMS warning light,
resulting from the tire air
pressure dropping due to
cold ambient temperature
will remain illuminated
even if the ambient tem-
perature rises. In this
case, it will also be nec-
essary to adjust the tire
air pressures. If the
TPMS warning light illu-
minates due to a drop in
tire air pressure, make
sure to check and adjust
the tire air pressures.
• Tires lose air natu-rally over time and
the TPMS cannot tell
if the tires are getting
too soft over time or
you have a fl at.
However, when you
find one low tire in a
set of four-that is an
indication of trouble;
you should have
someone drive the
vehicle slowly for-
ward so you can
inspect any low tire
for cuts and any
metal objects stick-
ing through tread or
sidewall. Put a few
drops of water in the
valve stem to see if it
bubbles indicating a
bad valve. Leaks
need to be
addressed by more
than simply reinflat-
ing the tire as leaks
are dangerous —
take it to your Toyota
dealer.
